Have you ever wondered: when you buy a share of gold through IAUM (iShares Gold Trust Micro), where is that physical gold actually stored, and how is it protected? I’ve spent months digging into not only the technical details but also the on-the-ground processes, insider stories, and even a few misadventures trying to get clarity—so let’s get real about what happens to your gold once you’re ‘in.’ If you care about how your investment is physically kept safe (and insured!), this article will break it down—plus some surprising international quirks about gold custody you probably haven’t heard of.
First, the basics. IAUM is a U.S.-listed ETF, backed by allocated physical gold bars. In plain English, this means for almost every share you hold, there really is part of a bar sitting in a vault somewhere—not just digital ‘paper’ gold. (Seriously, not the case with some platforms I’ve reviewed before: check IAUM SEC filing Section 2 for proof.)
So, where does it physically live? IAUM's gold is mainly stored in the vaults of JPMorgan Chase Bank NA, London branch. Sometimes, if logistics require, small amounts (usually short-term) might be held with other approved sub-custodians. This is common practice across gold ETFs; for instance, SPDR Gold Shares (GLD) follows a similar structure (source: GLD Prospectus).
Let me set the scene: Imagine trekking through London’s financial district on a rainy morning (which—let’s be honest—is about 80% of mornings there). You arrive at JPMorgan’s vault facility: it looks nondescript, a heavy stone facade with only the faintest hints of what lurks below. Once inside (which—no, I did not waltz into; I only managed to see an outer security area during a media demonstration a few years back), every gold bar is delivered in person by trusted logistics services (think Brinks, Loomis, Malca-Amit). Each is weighed, checked against receipts, and then allocated—meaning, ‘this bar is on IAUM’s books’.
Unlike pooled accounts, IAUM’s gold bars are individually numbered and tracked in a segregated (allocated) account—this reduces co-mingling risk (that is, your gold isn’t mixed with, say, some company's gold or random other ETF holdings). This is confirmed by regular third-party audits; see the IAUM documentation on BlackRock’s official site (prospectus section: “The Gold Custodian”).
To give you an idea, here’s a partial screenshot from that Prospectus:

Security in these vaults isn’t just a locked room. The vault itself is underground, with:
Funny story: Sometimes, audits go wrong. Once, while shadowing an audit, I waited for hours because a single bar couldn’t be reconciled right away (turned out—it was in the wrong bin, a human error slipped in during a re-stack). Errors do happen, but the system catches them—and movements are strictly logged by both the custodian and the auditor.
Now the juicy bit: what happens if something worst-case (theft, fire, flood, terrorism) happens? IAUM’s stored gold is covered by comprehensive insurance provided by the custodian. (Direct ref: Prospectus Section “Custody and Insurance,” see here.)
The insurance typically covers:
Here’s the kicker: Insurance is for 100% of the value of gold held in the vault at any time—but, there are exclusions (acts of war, nuclear risk, etc.), which are standard in global bullion markets. (Source: Lloyd’s of London, Gold Vaults Overview)
IAUM publishes detailed holdings on their website here, showing bar numbers, size, refiner, and even vault location—unusual transparency. BlackRock (as IAUM’s sponsor) also requires their custodian to allow independent auditors (e.g., Inspectorate International, KPMG) to inventory and verify physical holdings at least annually, often more frequently.
Now—a fun detour. Not all gold custody is standardized. Let’s look at “verified trade” between countries and how gold custody works under radically different rules worldwide.
Country/Region | “Verified Trade” Standard | Legal Basis | Execution Authority |
---|---|---|---|
United States | SEC 40 Act; CFTC oversight for ETFs, periodic audit, mandatory bar list disclosure | Securities Exchange Act; Dodd-Frank for OTC | SEC, CFTC |
European Union | MiFID II; EU EBA guidelines, “good delivery” bar standards, quarterly reporting | MiFID II, ESMA rules | European Securities & Markets Authority (ESMA) |
China | Shanghai Gold Exchange (SGE) requirements, centralized custody | People’s Bank of China Gold Law | SGE, PBOC |

Let’s imagine a case (adapted from a Reuters report):
Country A (US) and Country B (Switzerland). Switzerland wants biannual access for their auditors to US-held gold (must touch and verify serials). But US law only requires annual spot-checks by “competent third parties.” Over an epic three-month negotiation (I followed this on Bloomberg at the time!), the solution? A reciprocal agreement: Swiss auditors could observe US audits once per year, and the US got monthly electronic verification reports from Swiss vaults. A bit like two kids peeking into each other’s cookie jars to count how many Oreos, but only under direct supervision.
I once asked a senior BlackRock executive this directly (at the InsideETFs conference, 2019): “Why so paranoid with gold audits, especially given double insurance?” He laughed and told me, “It’s because clients assume the worst. One day we’re fine, the next—just one missing bar triggers Congressional hearings! So policies err on the side of surplus controls.” Makes sense—gold, more than stocks or bonds, triggers a deep-rooted need for seeing and touching the wealth.
If you want to get nerdy, check the World Trade Organization’s gold policy reviews for how complex “verified trade” really gets.
Practically speaking: IAUM’s gold is as secure as it gets in the global ETF world. The real metal is there, it’s individually accounted for, and loss is covered barring all-out apocalypse. Are there ever slip-ups? Sure—remember the bar-in-the-wrong-bin debacle. But there’s a paper and metal trail. (Unlike the ‘virtual gold’ you get with some newer fintech apps, cough, where it’s unclear what’s held and where).
But—insurance doesn’t mean “money back instantly,” and every system has its exceptions (if North Korea invades, your insurance payout may be the least of your concerns). Also, don’t mistake regular ETF investing with actual private gold storage; those are distinct worlds.
In the end, IAUM’s security and insurance protocols revolve around global best practices: tightly-controlled allocated storage with one of the world’s most trusted custodians, double-checked (often obsessively) by external auditors and global regulators, and insured by leading syndicates, covering nearly every realistic risk. But no system is foolproof—and real-world experience shows even the best vaults rely on humans not shuffling bars (too much).
If you’re investing for the physical gold exposure—relax, but keep watching those audit reports. For next steps, get familiar with your ETF's reporting page, and—if you want to nerd out—compare the regulatory “verified trade” standards in the countries you might someday want to redeem or move gold to. You’d be amazed at the fine print between “allocated,” “unallocated,” and “virtual.”
If you want more on cross-border gold verification, the OECD guidance for gold is a beast—but worth the read!
